DETAILED DESCRIPTION
[0032] A detailed description of one or more embodiments of the
disclosed apparatus and method are presented herein by way of
exemplification and not limitation with reference to the
Figures.
[0033] A transport refrigeration unit (TRU) is a refrigeration
device configured to cool a cargo space by blowing air from the
cargo space over a heat absorbing evaporator coil thereby cooling
the air, and returning it to the cargo space. A TRU can be designed
to meet a number of customer and application requirements, such as
the outer physical envelope of the TRU. The shape and overall
dimensions of a TRU must ensure that once installed on a trailer
there is adequate clearance for powered truck operation and
maintenance, e.g., turning, fueling, accessing truck compartments
and/or maintenance items, and the like. In some cases, these
requirements can limit the arrangement of components within the
allotted volume for the TRU. The resultant TRU layout can include
otherwise unnecessary protrusion into the trailer cargo space.
[0034] Unlike some trailers, railway cars are generally not subject
to swing radii or other powered truck maintenance activities.
Therefore the outer envelope of a refrigeration unit is less
constrained in a railway car application in comparison to trailer
application. However, when a TRU is installed flush to the side of
a railway car, the air outlet of the TRU can protrude into the
conditioned cargo space similar to a trailer installation. Due at
least in part to commonality of shipping sizes (e.g. shipping
pallets), any extension from the interior wall of a railway car
into the conditioned cargo space can reduce the cargo payload
(e.g., by an entire row of shipping pallets). Reduction in payload
can have a correspondingly negative impact on shipping cost, speed,
and capacity. To overcome at least this limitation an adapter frame
for attaching a TRU to a railway car is disclosed.
[0035] FIG. 1 is an illustration of a front view of a TRU 10. The
TRU 10 has an outer enclosure 20, a condenser air inlet 30, and
condenser air outlet 40. The TRU 10 can have additional interfaces
for power, fuel (e.g., diesel, LPG, CNG, and the like), drain (e.g.
condensate), control, communication, and the like. The TRU 10 can
be any suitable TRU 10 having an air inlet/outlet configured for
cooling the cargo space upon installation. For example, the TRU 10
can include a refrigeration unit such as the truck or trailer
refrigeration systems manufactured by Carrier Corporation, Palm
Beach Gardens, Fla., USA (e.g. Vector.TM. 8500, Vector.TM. 8600,
Vector.TM. 8611, X4.TM. 7300, X4.TM. 7500, Supra.RTM. 660,
Supra.RTM. 760, Supra.RTM. 860, Supra.RTM. 960, and the like).
[0036] The TRU 10 has a width measured along the w-dimension, a
height measured along the h-dimension, and a depth measured along
the d-dimension in the attached figures. The outside of the TRU 10
can be box shaped or can include aerodynamic features as the
outside surface, such as curved edges. In any embodiment the TRU
can include rounded or contoured edges, between the face 11 and top
12, bottom 14, and/or sides 16/18 of the TRU 10.
[0037] FIG. 2 is an illustration of a rear view of a TRU 10 with
the outer enclosure 20 removed. The back side 13 (cargo side) of
the TRU 10 can be flat, or have a surface shaped corresponding to
the outside surface of a trailer. The TRU can have a protruding
evaporator section 70 having the cargo air inlet 50 (which can be
located for example under the protruding evaporator section 70) and
one or more refrigerated cargo air outlets 60. As shown in FIG. 3,
the protruding evaporator section 70 can include air outlet
extensions 72 which can protrude further from the main body of TRU
10 than the protruding evaporator section 70 and can define a
distal end 66 of the protruding evaporator section.
[0038] For trailer applications, the protruding evaporator section
70 can have a width (extending in the w dimension of the attached
figures) of about 60 inches to about 80 inches, or about 65 inches
to about 68 inches, or about 66.3 inches, a height (extending along
the h dimension in the attached figures) of about 40 inches to
about 60 inches, or about 44 inches to about 48 inches, or about
45.3 inches, and a protruding distance (extending along the d
dimension of the attached figures) of about 1 inch to about 15
inches, or about 6 inches to about 10 inches, or about 8.2
inches.
[0039] For truck applications, the protruding evaporator section 70
can have a width of about 40 inches to about 60 inches, or about 48
inches to about 52 inches, or about 48.2 inches, a height of about
8 inches to about 20 inches, or about 10 inches to about 14 inches,
or about 13 inches, or about 11.4 inches, and a protruding distance
of about 1 inch to about 32 inches, or about 20 inches to about 32
inches, or about 28.8 inches, or about 24.8 inches. In an
embodiment the protruding evaporator section 70 has a width of
about 48.2 inches, a height of about 13 inches and a protruding
distance of about 28.8 inches. In an embodiment the window 420 has
a width of about 48.2 inches, a height of about 11.4 inches and a
protruding evaporator distance of about 24.8 inches.
[0040] In truck/trailer applications the TRU 10 is flush mount to
the outside surface of a trailer 100 as shown in FIG. 4. The
trailer 100 is configured with an opening 102 for receiving the
protruding evaporator section 70. Once installed the distal end 66
extends past the interior surface 104 of a trailer wall 106.
Although undesirable, the size of the refrigeration unit components
(e.g., compressor, evaporator coil, condenser coil, expansion
device, plumbing, controller, and the like) and limited volume they
may occupy outside the trailer can result in pushing protruding
evaporator section 70 into the cargo space.
[0041] FIG. 5 is an illustration of a TRU 10 installed directly
onto a wall of a railway car 200 without the use of the inventive
adapter frame as disclosed herein. In this installation, the
protruding evaporator section 70 extends past an interior surface
204 of the railway car 200 and creates an obstructed volume 250
(shaded area in FIG. 5) of the cargo volume 220 of the railway car
200. The size of the obstructed volume can be reduced through the
use of the disclosed adapter frame 400, which can act to shift the
protruding evaporator section 70 out of the opening 102 (in a
negative direction along the d dimension in the attached figures)
and away from the railway car cargo volume 220. Even small outward
movement of the protruding evaporator section 70 from the cargo
volume 220 can create significant advantages in payload capacity of
the cargo volume 220. In some cases, this can allow for an entire
row of shipping pallets to be added to a railway car's cargo volume
220.
[0042] FIG. 6 is an illustration of an adapter frame 400 having a
plurality of structural segments 402 fastened together to form a
window 420 and a supporting section 440. The plurality of
structural segments 402 can be any shape corresponding to the
outside surface of a railway car 200 and the back side 13 of a TRU
10. The plurality of structural segments 402 can be formed from any
suitably strong material capable of mounting and supporting a TRU
10 to a railway car 200. For example the structural segments 402
can be made of steel, aluminum, iron, alloys thereof, or a
combination comprising at least one of the foregoing. In an example
the structural segments 402 can be made of a polymer including for
example polyethylene (PE), acrylonitrile butadiene styrene (ABS)
polymer, high-density polyethylene (HDPE) polymer, and the like,
and copolymers thereof. In an example the structural segments 402
can be made of a polymer composite, where the composite material
includes a polymer resin such as a polymer previously mentioned and
a woven, continuous, or chopped structural fiber, e.g., glass
fiber, carbon fiber, aramid fiber, or the like.
[0043] The plurality of structural segments 402 can have any cross
sectional shape, for example, the cross-sectional shape of any one
or more segment of the plurality of structural segments can be
quadrilateral (e.g., square, rectangular, and the like),
triangular, other simple closed polygons, I-shaped, H-shaped,
C-shaped, U-shaped, T-shaped, and the like. For example, the
plurality of structural segments 402 can be linear, e.g., not
having appreciable curvature in a given plane. The cross-sectional
thickness T (extending along the t axis in the attached figures) of
the adapter can
[0044] The plurality of structural segments 402 can be fastened in
any suitable way to secure the segments and form the adapter frame
400. For example, the plurality of structural segments 402 can be
welded (arc, ultrasonic, and the like), bolted or otherwise secured
together to form the window 420 and the supporting section 440. In
another example, the structural segments 402 can be formed
integrally as a single unitary structure such as die cast, polymer
molding, co-molding, multi shot molding, or other molding process.
The window 420 can have any shape, for example it can have a shape
corresponding to the outer dimensions of the protruding evaporator
section 70 such that the protruding evaporator section 70 can
slidably fit into the window 420 for purposes of installing and
removing the TRU 10 from the adapter frame 400. For example, the
window 420 can have a quadrilateral shape, such as square,
rectangular, trapezoidal, and the like. The window 420 can
optionally include additional framing extending from a front/rear
surface (405/406) of the adapter frame 400 for added structural
support of the window 420. Additional framing can be used for
securing the protruding evaporator section 70 to the window 420.
For example, the window 420 can be formed of steel box beam and an
additional steel frame formed of steel having an L-shaped cross
section welded to, and extending from, a front surface 405 of the
adapter frame 400. The L-shape can provide a flange for fastening
the TRU 10 or the railway car 200 to the adapter frame 400.
[0045] In an example, the window 420 is rectangular, the window has
a width dimension W (extending along the w axis in the attached
figures) that is larger than the height dimension H (extending
along the h axis in the attached figures) and the supporting
section 440 includes two or more truss members 422 spanning from an
edge of the window 420 to a corresponding edge of the supporting
section 440.
[0046] Corresponding to the dimensions of the protruding evaporator
section 70 mentioned previously for trailer applications, the
window 420 of the adapter frame 400 can have a width W of about 60
inches to about 80 inches, or about 65 inches to about 68 inches,
or about 66.8 inches, a height H of about 40 inches to about 60
inches, or about 45 inches to about 48 inches, or about 46 inches,
and a thickness (extending along the d dimension of the attached
figures) of about 1 inch to about 16 inches, or about 2 inches to
about 10 inches, or about 8.2 inches. In an embodiment the window
420 of the adapter frame 400 has a width of 66.8 inches, a height
of 46 inches and a thickness of between 1 and 16 inches.
[0047] Corresponding to the dimensions of the protruding evaporator
section 70 mentioned previously for truck applications, the window
420 of the adapter frame 400 can have a width W of about 40 inches
to about 60 inches, or about 48 inches to about 52 inches, or about
49 inches, a height H of about 8 inches to about 20 inches, or
about 10 inches to about 14 inches, or about 13 inches, or about
11.4 inches and a thickness (extending along the d dimension of the
attached figures) of about 1 inch to about 32 inches, or about 1
inches to about 16 inches, or about 10 inches, or about 8 inches,
or about 6 inches. In an embodiment the window 420 of the adapter
frame 400 has a width of 49 inches, a height of 13.8 inches and a
thickness of between 1 and 16 inches. In an embodiment the window
420 of the adapter frame 400 has a width of 49 inches, a height of
12.2 inches and a thickness of between 1 and 16 inches.
[0048] In another example, as shown in FIG. 7, the supporting
section 440 can include a plurality of truss members 423. The
plurality of truss members 423 can extend from a bottom structural
segment 415 to a mid-spanning segment 417, which can also
constitute an edge, and optionally the bottom edge of the window
420.
[0049] The adapter frame 400 can include a corner support 426
disposed between adjacent structural segments 402. The corner
support 426 can be used to add rigidity to the adapter frame 400
and reinforce the structural segments 402 against deformation.
[0050] The adapter frame 400 can include TRU side fastening
features 410 for securing the adapter frame 400 to a TRU 10. The
adapter frame 400 can include rail car side fastening features 411
for securing the adapter frame 400 to a railway car 200. The TRU
side fastening features 410 can be disposed along one face of the
adapter frame 400, for example, the front surface 405 of the
adapter frame 400. The rail car side fastening features 411 can be
disposed on an opposing side of the adapter frame 400, for example
the rear surface 406. The TRU side fastening features 410 and the
rail car side fastening features 411 can be any suitable mechanical
fastener, for example a threaded stud, a captured nut, a slot or
opening for accepting a bolt, a weld stud, a flange, a tab, or a
combination including at least one of the foregoing. For example,
the adapter frame 400 can include a threaded stud extending from a
front surface 405 of the adapter frame 400, along the depth
dimension, for inserting into a corresponding opening on the TRU 10
which can accept the treaded stud and allow for movement of a
washer and/or nut to securely fasten the adapter frame 400 to the
TRU 10.
[0051] FIG. 8 shows a side view of a TRU 10 and adapter frame 400
installed onto a railway car 200. The adapter frame 400 can be used
to position the TRU further away from the railway car 200 and
reduce or eliminate the distance of TRU protrusion into the cargo
volume 220. By using an adapter frame 400 to mount the TRU to the
railway car, the obstructed volume 250 can be reduced or eliminated
completely offering a corresponding improvement in available cargo
volume 220. The use of an adapter frame 400 allows for ordering the
sequence of assembly in the most beneficial way to the installer.
The adapter frame 400 can first be installed onto a TRU 10, then
the TRU and adapter frame securely mounted to a railway car 200.
Or, the adapter frame 400 can first be installed on the railway car
200 then the TRU 10 can be mounted to the adapter frame 400.
[0052] FIG. 9 illustrates an installation method that can be
employed using the adapter frame 400. A first step 500 includes
attaching an adapter frame 400 onto a railway car 200 to form a
combined adapter frame and railway car. The attachment can be made
using any suitable fastening method, for example the adapter frame
400 can be welded to the railway car 200, the plurality of railway
car side fastening features 411 can be relied on to secure the
adapter frame 400 to a wall of a railway car 200. By way of further
example, threaded studs extended from the adapter frame 400 could
be inserted into corresponding holes in the railway car 200 and
nuts fastened thereto to secure the adapter frame 400 to the
railway car 200. The TRU 10 can them be installed to the combined
adapter frame and railway car in a second step 501 using any
suitable fastening method, for example utilizing the TRU car side
fastening features 410.
[0053] FIG. 10 illustrates an installation method that can be
employed using the adapter frame 400. A first step 600 includes
attaching an adapter frame 400 to a TRU 10 to form a combined
adapter frame and TRU. The attachment can be made using any
suitable fastening method, for example the plurality of TRU side
fastening features 410 can be relied on to secure the adapter frame
400 and the TRU 10. The combined adapter frame and TRU can then be
installed to a railway car 200 in a second step 601 using any
suitable fastening method, for example utilizing the railway car
side fastening features 411. During and after installation the
window 420 of the adapter frame 400 can be aligned with an opening
in the wall of the railway car 200.
[0054] As part of the installation process the opening 102, the
adapter frame 400, the TRU 10, or a combination including at least
one of the foregoing can be prepared with a gasket and/or seal
